Period like cramps when I woke up

I’m 37w6d and I woke up with period cramps. Is this normal? I’ve had tightening on the top of my stomach for the last two days a lot (not constant enough to track) and diarrhea 3x a day for the last two days, continuing into today (so 3 days now). I’ve yet to have any mucus plug or show🤷🏻‍♀️😩

Anyone wanna reassure me baby’s fine? I know it’s not worth a call into doctors as it’s probably normal and I’m freakin out because I’m a Ftm!

TIA
